Plugin seems to need reset often

Hi. I am using your mod on my 2nd server now and still finding the same issue. the mod works great for a liitle while but after a unknown amount of time (normally the next time I or another joins the server the following day) we are again taking cold or heat effect. if I reload the mod everything works again but always seems to stop working by the next day. the config is only 3 lines so I do not think I messed it up, any help would be greatly welcomed :)

You could do what i did for one of my plugins that would stop working after an undetermined amount of time, and that is use TimedExecute plugin to reload the plugin after a set amount of time , it only takes a few seconds to unload and then reload the plugin and would have a minimal effect on players,

yeah, this plugin stops working,  damage comes on from temp, we reload it, it works for a while before stopping again.  Really really needs to be updated.  Please.
